Letters Patent No. 110,912, dated January 10, 1871.

IMPROVEMENT `IN no1-Am! ENGINES.

The Schedule referred to in there Patent and mung part o! the lame.

` .To allwh'om it may concern.-

on,"making a part of this specification.

My present invention is intended as an improvement uponthe centrifugalrotary 'engine for which "Letters" Patent were granted to me October 4,1870;

aml

It consists in tbe-construction and arrangement of an outer and an innerwheel, the outer wheel being stationary vwhile the inner revolves.

In order to enable others skilled in the art to I which my inventionappertains to make and use the same, I will uo'w proceed to describe its`construction and operation, referring to the annexed drawing, invwhich-' Figure 1 is a longitudinal vertical section, and Figure 2 atransverse vertical' section of my iin- A represents the outer wheel orcircula-r casing,

Erovided on one side in the center with asteam-chest,

intov which the steam is admitted through the pipe C.

Around the entire inner circumference of the wheel or casing A, which isstationary, is placed a series of buckets, a a, as shown in g. 1.

In the center of the casing A' is placed a circular box or chest, D,provided with two journals b and d., The journal b passes4 through thecenter ofthe offsde ot' the casingfand has a. bearingat any suitablepoint on the outside thereof. u

Unthis journal, which is solid, is placed a pulley or cog-wheel, E, tocommunicate motion to any machinery desired to be driven. llie otherfournal, d, is hollow, and passes into the steam-chest where it has itsbearing in adisk, e,

attached by suitable arms Vto the nut j, which closes the outer end ofsaid steam-chest.

Thus, a communication is established between the steamfchest B and thebox 1), so that the steam admitted into said ohest may pass through thehollow journal dintothe box D.

From the box D two hollow arms h, curved, as shown, lead to two bucketsfi formed in the inner rim or wheel G. Y

as to form with each of the buckets a in .succession a steam-box, intowhich the'steam passes from or through' 'the hollow arms h. causingy theinner wheel G to revolve in a direction opposite to that at which thesteam is admitted.

lhe buckets-11 t are further so arrangedv with relation to eachotherthat when one of them forms such a steam-box as just mentioned theother isopen, and cioe versa, thus alternating to cause the steam toproduce said rotar;r motion ofthe wheel. Y v

The -steam is exhausted b y passing through holes in the wheel G tdtheinside thereof; and thence through the pipe H to any point desire Havingthus fully described my invention,

What I claim as new, and desire to secure -by Letters Patent, is

1. The stationary wheel or' casing A, provided with aseriesof'buekets, a@extending around itsentire revolving wheelG provided with two bucketst' t', 4all constructed and operating substantially'as aud`for thepurposes herein set forth.l

2. '.lhe combination of the outer stationary wheel d, disk e, armslth,inner-revolving wheel G, buckets arranged to operate substantially asand for the purposes herein set forth.

" InV testimony thatI claim the foregoing, I have hereunto set my handthis 3d day of November, 1870.
